Subject: [PATCH] Call super().__init__() in PoolScheduler __init__

Subclasses of `PoolScheduler` can't work with the Pool because a missing attribute `__local_free_head` causes `__addLocal__` to raise an AttributeError. Calling `super().__init__()` in the `PoolScheduler`  `__init__` method seems to fix this since the `Chare` class sets this attribute in its `__init__()`.
